Description

Technical Field

[0001] This invention relates to the field of copper wire stranding machine technology, specifically to a copper wire stranding machine with uniform stranding. Background Technology

[0002] Copper wire stranding machines are key equipment in the manufacture of wires and cables. They are used to spirally strand multiple copper single wires together at a certain pitch and direction to form conductor cores. In particular, copper wire stranding machines are needed in the production of cross-linked polyethylene insulated power cables to ensure the tightness of the cross-linked polyethylene insulated power cable cores.

[0003] Existing copper wire stranding machines are prone to wire breakage at the mold closing position, especially in the processing of cross-linked polyethylene insulated power cable cores. Traditional devices cannot automatically detect and respond to this, requiring operators to visually inspect or manually stop the machine after hearing an abnormality. After a wire breakage, the copper wire becomes scattered and tangled, making cleaning time-consuming and labor-intensive.

[0004] To address the aforementioned issues, we propose a copper wire stranding machine that produces uniformly stranded wires. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a copper wire stranding machine with uniform stranding. The device utilizes a concave wheel for the conductor to maintain tension via a spring. When the wire breaks, the tension disappears, and the spring automatically pushes the moving hole block to slide, achieving mechanical automatic detection of wire breakage without the need for sensors and control systems.

[0006] Furthermore, the moving hole block drives the actuating plate to rotate via the first connecting groove block and the pushing linkage. The actuating plate drives the rubber semicircular block on the N-type clamp block to approach the concave wheel of the wire through the combination block and the second connecting groove block, clamping the copper wire at the broken point and preventing the copper wire from scattering.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a copper wire stranding machine with uniform stranding, comprising a motor base, two wire frame bases provided on the right side of the motor base, a copper wire frame provided between the two wire frame bases, and a first protective component provided at multiple wire outlets on the right side of the surface of the copper wire frame.

[0008] A mold-closing base is provided on the right side of the wire frame base. A mold-closing column block is fixedly installed on the top of the mold-closing base. Second protective components are provided on both the front and rear sides of the mold-closing column block on the right side of the mold-closing base.

[0009] The first protective component includes two connecting shells fixedly installed on the right side of the copper wire frame surface. Sliding grooves are provided on opposite sides of the two connecting shells. Limiting rods are fixedly installed on the inner walls of the two sliding grooves. Moving holes are slidably installed on the rod walls of the two limiting rods. Wire concave wheels are rotatably installed on opposite sides of the two moving holes. Springs are sleeved on the rod walls of the two limiting rods between the moving holes and the sliding grooves. Limiting components are provided on the side of the inner wall of the two sliding grooves away from the wire concave wheels.

[0010] Furthermore, the first protective component is used to transport the copper wire of the copper wire frame; the copper wire frame is equipped with structures such as a winch and a winch cage, and the winch and winch cage structures in the copper wire frame are existing technologies, which will not be described in detail in this application.

[0011] An output motor is fixedly installed on the top of the motor base, and a power shaft is fixedly installed on the output end of the output motor. The power shaft passes through the left wire frame base and is rotatably connected to the left wire frame base. A conveying perforated disc is rotatably installed on the top of the right wire frame base. The right end of the power shaft is fixedly connected to the center of the surface of the conveying perforated disc. The axis of the mold clamping column block and the axis of the power shaft are located on the same horizontal line and are coaxially arranged to ensure the stability and uniformity of the copper wire stranding process.

[0012] Furthermore, an extension rod is fixedly installed on one side of each hole on the right side of the conveying multi-hole disc, and a wire feed ring is fixedly installed at the right end of each extension rod; the wire feed ring and the extension rod are used to prevent the copper wire from contacting the wire frame base during output, so as to avoid damage to the surface of the copper wire.

[0013] Furthermore, the multiple wire outlets, several wire feeding rings, and multiple inner wall edges of the conveying multi-hole disc on the right side of the copper wire frame are all chamfered to avoid damaging the surface of the copper wire.

[0014] Furthermore, the movable holes are slidably attached to the inner walls of the corresponding sliding grooves, and the inner concave wall of the conductor concave wheel is set on one side of the copper wire frame outlet, which is used to guide the copper wire through the conductor concave wheel to the conveying multi-hole disc. The elastic force of the spring can ensure that the conductor concave wheel is always close to the copper wire frame outlet.

[0015] Furthermore, the limiting component includes a first opening on one side of the inner wall of the sliding groove, a first connecting groove block is slidably installed on the inner wall of the first opening, a push connecting rod is rotatably installed on the inner wall of the first connecting groove block, and two support blocks are fixedly installed on the side of the inner wall of the connecting shell away from the first opening. A toggle plate is rotatably installed on the two support blocks on opposite sides, and the surface of the toggle plate is rotatably connected to the end of the push connecting rod.

[0016] Two assembly blocks are fixedly installed on the side of the actuating plate away from the first opening. A second connecting groove block is rotatably installed on the surface of each of the two assembly blocks. A second opening is opened on one side of each of the two second connecting groove blocks on the inner wall of the connecting shell. An N-type clamping block is fixedly installed on the surface of the four corresponding second connecting groove blocks. A rubber semicircular block is fixedly installed on the upper side of the inner wall of the wire concave wheel on the inner wall of the N-type clamping block.

[0017] Furthermore, a starting ramp is fixedly installed on both opposite sides of the two support blocks. The starting ramp is located on the side close to the first connecting groove block. A remote control switch is fixedly installed at the bottom of the starting ramp. When the wire concave wheel is unloaded, the toggle plate rotates and presses the remote control switch, causing the whole machine to stop.

[0018] Furthermore, the surface of the first connecting groove block is fixedly connected to the surface of the moving hole block, and the surfaces of the two second connecting groove blocks extend to the surface of the connecting shell through the second through-hole. A reset rotary spring is provided between the actuating plate and the support block. When the wire concave wheel is unloaded, the reset rotary spring causes the rubber semicircular block on the N-type clamping block to approach the wire concave wheel, so as to clamp the copper wire when the wire breaks at the mold closing point and prevent the copper wire from scattering.

[0019] Furthermore, the second protective component includes an L-shaped support block fixedly installed on the surface of the mold base. A fixing sleeve is fixedly installed on the upper and lower sides of the surface of the L-shaped support block. An electromagnet is provided on the inner wall of each fixing sleeve. A magnetic suction rod is slidably installed on the side of the inner wall of the fixing sleeve away from the electromagnet.

[0020] A pulling block is fixedly installed at the end of the magnetic rod away from the electromagnet. A semi-circular clamping block is fixedly installed on the opposite sides of the two corresponding upper and lower pulling blocks. A positioning rod is slidably installed on the surface of the corresponding pulling blocks on the front and rear sides. A push spring is sleeved on the side of the positioning rod wall near the L-shaped support block.

[0021] Furthermore, the front and rear ends of the positioning rod are fixedly connected to the surfaces of the front and rear L-shaped support blocks, respectively. The interior of each semi-circular clamp is equipped with a rubber pad. The electromagnet is magnetically connected to the magnetic suction rod. When the whole machine is powered on, the electromagnet is energized and drives the pulling block on the magnetic suction rod to move through the magnetic attraction force, so that the semi-circular clamp is away from the stranded copper wire. When the whole machine is powered off, the elastic force of the push spring pushes the two semi-circular clamps to move relative to each other, clamping the stranded copper wire to prevent the copper wire from detaching, being damaged or scattered. Since the core of the cross-linked polyethylene insulated power cable needs to be kept tight and uniform during the stranding process, wire breakage at the mold closing position is a common problem. This application solves this problem by automatically clamping the copper wire when the power is off through the above structure.

[0022] Compared with the prior art, the present invention provides a copper wire stranding machine with uniform stranding, which has the following beneficial effects:

[0023] 1. This device uses a concave wheel on the wire to maintain tension through a spring. When the wire breaks, the tension disappears, and the spring automatically pushes the moving hole block to slide, realizing mechanical automatic detection of wire breakage without the need for sensors and control systems.

[0024] Furthermore, the moving hole block drives the actuating plate to rotate via the first connecting groove block and the pushing linkage. The actuating plate drives the rubber semicircular block on the N-type clamp block to approach the concave wheel of the wire through the combination block and the second connecting groove block, clamping the copper wire at the broken point and preventing the copper wire from scattering.

[0025] 2. The device triggers the automatic shutdown of the entire machine by simultaneously pressing the remote control switch when the toggle plate rotates, making it convenient for operators to handle wire breakage faults in a timely manner;

[0026] A reset spring is provided between the actuating plate and the support block. When there is no load on the guide wheel, it can assist the rubber semicircular block on the N-type clamp block to move closer to the guide wheel.

[0027] 3. When the power is off, the electromagnet loses power, which pushes the spring to move the semi-circular clamping block relative to each other, clamping the stranded copper wire to prevent the copper wire from falling off and scattering after the power is off, thus ensuring that the core is tight and uniform.

[0028] The copper wire rack outlet, wire feeding ring, and inner edge of the conveyor multi-hole tray are all chamfered to avoid damage to the copper wire surface and improve product quality. Attached Figure Description

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see Figures 1 to 8 This embodiment of a copper wire stranding machine for uniform stranding includes a motor base 1, two wire frame bases 2 are arranged on the right side of the motor base 1, and a copper wire frame 3 is arranged between the two wire frame bases 2. A first protective component 4 is provided at multiple wire outlets on the right side of the surface of the copper wire frame 3. The first protective component 4 is used to transport the copper wire of the copper wire frame 3. The copper wire frame 3 is provided with a winch and a winch cage, etc. The winch and winch cage structures in the copper wire frame 3 are existing technologies and will not be described in detail in this application.

[0042] An output motor 101 is fixedly installed on the top of the motor base 1. A power shaft 102 is fixedly installed on the output end of the output motor 101. The power shaft 102 passes through the left wire frame base 2 and is rotatably connected to the left wire frame base 2. A conveying perforated disc 103 is rotatably installed on the top of the right wire frame base 2. The right end of the power shaft 102 is fixedly connected to the center of the surface of the conveying perforated disc 103. The axis of the mold clamping column block 6 and the axis of the power shaft 102 are located on the same horizontal line and are coaxially arranged to ensure the stability and uniformity of the copper wire stranding process.

[0043] An extension rod 104 is fixedly installed on one side of each hole on the right side of the conveying multi-hole disc 103, and a wire feeding ring 105 is fixedly installed on the right end of each extension rod 104. The wire feeding ring 105 and the extension rod 104 are used to prevent the copper wire from contacting the wire frame base 2 during output, so as to avoid damage to the surface of the copper wire. The multiple wire outlets on the right side of the copper wire frame 3, the multiple wire feeding rings 105, and the multiple inner wall edges of the conveying multi-hole disc 103 are all chamfered to avoid damage to the surface of the copper wire.

[0044] A mold clamping base 5 is provided on the right side of the right wire frame base 2. A mold clamping column block 6 is fixedly installed on the top of the mold clamping base 5. A second protective component 7 is provided on both the front and rear sides of the mold clamping column block 6 on the right side of the mold clamping base 5.

[0045] The second protective component 7 includes an L-shaped support block 701 fixedly installed on the surface of the mold base 5. A fixing sleeve 702 is fixedly installed on the upper and lower sides of the surface of the L-shaped support block 701. An electromagnet 703 is provided on the inner wall of each fixing sleeve 702. A magnetic suction rod 704 is slidably installed on the side of the inner wall of the fixing sleeve 702 away from the electromagnet 703.

[0046] A pull block 705 is fixedly installed at the end of the magnetic rod 704 away from the electromagnet 703. A semi-circular clamping block 706 is fixedly installed on the opposite sides of the two corresponding pull blocks 705. A positioning rod 707 is slidably installed on the surface of the corresponding pull blocks 705 on the front and rear sides. A push spring 708 is sleeved on the side of the rod wall of the positioning rod 707 near the L-shaped support block 701.

[0047] The front and rear ends of the positioning rod 707 are fixedly connected to the surfaces of the front and rear L-shaped support blocks 701, respectively. The interior of the semi-circular clamping blocks 706 is equipped with rubber pads. The electromagnet 703 is magnetically connected to the magnetic suction rod 704. When the whole machine is powered on, the electromagnet 703 is energized and drives the pulling block 705 on the magnetic suction rod 704 to move through the magnetic attraction force, so that the semi-circular clamping blocks 706 are away from the stranded copper wire. When the whole machine is powered off, the elastic force of the push spring 708 pushes the two semi-circular clamping blocks 706 to move relative to each other, clamping the stranded copper wire to prevent the copper wire from falling off, being damaged or scattered. Since the core of the cross-linked polyethylene insulated power cable needs to be kept tight and uniform during the stranding process, wire breakage at the mold closing position is a common problem. This application solves this problem by automatically clamping the copper wire when the power is off through the above structure.

[0048] The first protective component 4 includes two connecting shells 401 fixedly installed on the right side of the surface of the copper wire frame 3. Each of the two connecting shells 401 has a sliding groove 402 on its opposite sides. A limit rod 403 is fixedly installed on the inner wall of each of the two sliding grooves 402. Moving blocks 404 are slidably installed on the walls of the two limit rods 403. Wire concave wheels 405 are rotatably installed on the opposite sides of the two moving blocks 404. The moving blocks 404 slide against the inner wall of their respective sliding grooves 402. The inner concave wall of the conductor concave wheel 405 is located on one side of the outlet of the copper wire frame 3, which guides the copper wire through the conductor concave wheel 405 to the conveying multi-hole disc 103. The elastic force of the spring 406 ensures that the conductor concave wheel 405 is always close to the outlet of the copper wire frame 3. The walls of the two limiting rods 403 are fitted with springs 406 between the moving hole block 404 and the sliding groove 402. The inner walls of the two sliding grooves 402 are provided with limiting components 8 on the side away from the conductor concave wheel 405.

[0049] The limiting component 8 includes a first opening 801 opened on one side of the inner wall of the sliding groove 402. A first connecting groove block 802 is slidably installed on the inner wall of the first opening 801. A push connecting rod 803 is rotatably installed on the inner wall of the first connecting groove block 802. Two support blocks 804 are fixedly installed on the side of the inner wall of the connecting shell 401 away from the first opening 801. A toggle plate 805 is rotatably installed on the two support blocks 804 on opposite sides.

[0050] Two assembly blocks 806 are fixedly installed on the side of the toggle plate 805 away from the first through-hole 801. The surfaces of the two assembly blocks 806 are rotatably mounted with second connecting groove blocks 807. The inner wall of the connecting shell 401 is provided with second through-holes 808 on one side of the two second connecting groove blocks 807. The surfaces of the four corresponding second connecting groove blocks 807 are fixedly mounted with N-type clamping blocks 809. The inner wall of the N-type clamping blocks 809 is fixedly mounted with a rubber semi-circular block 810 on the upper side of the inner wall of the wire concave wheel 405.

[0051] Two support blocks 804 are fixedly mounted on opposite sides with a starting ramp 811. The starting ramp 811 is located on one side close to the first connecting slot block 802. A remote control switch 812 is fixedly mounted on the bottom of the starting ramp 811. When the wire concave wheel 405 is unloaded, the toggle plate 805 rotates and presses the remote control switch 812 to stop the whole machine.

[0052] The surface of the first connecting groove block 802 is fixedly connected to the surface of the moving hole block 404. The surfaces of the two second connecting groove blocks 807 extend to the surface of the connecting shell 401 through the second through 808. A reset rotary spring 8051 is provided between the actuating plate 805 and the support block 804. When the wire concave wheel 405 is unloaded, the reset rotary spring 8051 causes the rubber semicircular block 810 on the N-type clamping block 809 to approach the wire concave wheel 405 so as to clamp the copper wire when the wire breaks at the mold closing point and prevent the copper wire from scattering.

[0053] The advantages of this device compared to existing devices are as follows:

[0054] The wire concave wheel 405 is kept taut by the spring 406. When the wire breaks, the tension disappears and the spring 406 automatically pushes the moving hole block 404 to slide, realizing the mechanical automatic detection of wire breakage.

[0055] The movable hole block 404 drives the actuating plate 805 to rotate via the first connecting groove block 802 and the push connecting rod 803. The actuating plate 805 drives the rubber semicircular block 810 on the N-type clamping block 809 to approach the wire concave wheel 405 through the combination block 806 and the second connecting groove block 807, clamping the copper wire at the broken point.

[0056] When the toggle plate 805 rotates, it simultaneously presses the remote control switch 812, triggering the automatic shutdown of the entire machine.

[0057] A reset rotary spring 8051 is provided between the actuating plate 805 and the support block 804. During normal conveying, the N-type clamp 809 is kept away from the wire concave wheel 405, so as not to affect the passage of copper wire.

[0058] When the whole machine is powered off, the electromagnet 703 loses power, which pushes the spring 708 to move the semi-circular clamp 706 relative to each other, clamping the stranded copper wire to prevent the copper wire from scattering after the power is off.

[0059] The working principle of the above embodiments is as follows:

[0060] Before the device is started, the copper wires on the copper wire frame 3 are led out through the outlet and pass through the inner wall of the conductor concave wheel 405 of the first protective component 4, the hole of the conveying multi-hole disc 103 and the wire feeding ring 105 in sequence, and finally enter the mold closing column block 6 for twisting. The multiple outlets on the right side of the copper wire frame 3, the wire feeding ring 105 and the inner wall edge of the conveying multi-hole disc 103 are all chamfered to avoid damaging the surface of the copper wires.

[0061] After the device is started, the output motor 101 at the top of the motor base 1 drives the power shaft 102 to rotate. The power shaft 102 drives the conveying perforated disk 103 on the right wire frame base 2 to rotate. When the conveying perforated disk 103 rotates, the extension rod 104 and the wire feeding ring 105 on its right side drive multiple copper wires to revolve around the axis of the power shaft 102. The copper wires converge and twist together under the guidance of the mold closing column 6 to form a compact and uniform cable core. The axis of the mold closing column 6 is coaxial with the axis of the power shaft 102 to ensure the stability and uniformity of the twisting process.

[0062] During the copper wire transport process, the conductor concave wheel 405 of the first protective component 4 always maintains a tendency to be close to the outlet of the copper wire frame 3 under the elastic force of the spring 406, which tensions and guides the copper wire to prevent it from becoming loose or deviating. After the copper wire passes through the inner concave wall of the conductor concave wheel 405, it enters the conveying multi-hole disc 103.

[0063] When a wire breaks at the mold closing position, the tension on the wire concave wheel 405 disappears, and the spring 406 pushes the moving hole block 404 to move along the limit rod 403. The moving hole block 404 drives the first connecting groove block 802 to move. The first connecting groove block 802 pushes the actuating plate 805 to rotate around the support block 804 through the pushing connecting rod 803. When the actuating plate 805 rotates, it drives the N-type clamping block 809 to move through the combination block 806 and the second connecting groove block 807, so that the rubber semicircular block 810 approaches the wire concave wheel 405 and clamps the copper wire at the broken point to prevent the copper wire from scattering.

[0064] At the same time, the rotating toggle plate 805 presses the remote control switch 812 at the bottom of the inclined plate 811 to trigger the machine to stop, so that the operator can deal with the wire breakage fault in time. When the copper wire is being conveyed normally, the conductor concave wheel 405 is overcoming the elastic force of the spring 406 under the action of the copper wire tension, and the N-type clamp 809 moves away from the conductor concave wheel 405, which does not affect the normal passage of the copper wire, and the remote control switch 812 will not be triggered. When the device initially conveys the copper wire, the operator needs to pull the copper wire to twist it, so as to provide an initial force to the conductor concave wheel 405 to make the N-type clamp 809 move away from the conductor concave wheel 405.

[0065] During the stranding process, the second protective component 7 is used to clamp and protect the stranded cable core when the power is off. When the whole machine is powered on and working normally, the electromagnet 703 in the fixed sleeve 702 is energized and generates magnetic attraction force, attracting the magnetic rod 704 to move towards the electromagnet 703. The magnetic rod 704 drives the semi-circular clamp 706 away from the stranded copper wire through the pulling block 705, without affecting the normal stranding and transportation of the copper wire.

[0066] When the machine is unexpectedly powered off, the electromagnet 703 loses power and the magnetic attraction disappears. The elastic force of the spring 708 pushes the front and rear pull blocks 705 to slide along the positioning rod 707, causing the upper and lower semi-circular clamping blocks 706 to move relative to each other, clamping the stranded copper wire and preventing the copper wire from falling off, being damaged or scattered due to loss of tension. This effectively solves the problem of the core becoming loose due to wire breakage at the mold closing position.

[0067] After the copper wires are twisted together by the die-clamping block 6, they form a compact and uniform cross-linked polyethylene insulated power cable core, which is then transported to the subsequent processes.

[0068] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
